i need to know if any one has done or can tell me if i will have a problem w/ putting a b20 head from a crv on to my b18a? warped the b18 head. im not sure if will work because of the 84mm combustion and the b18 80mm

thanx :

 

Its the same as a B18B, it'll work fine. The combustion chambers are only 81mm, same as a stock bore B18A.

 

the only difference betwwen the B18 and 20 is the intake cam and intake manifold

 

hows the cam different please mrhalo
